Emergency in Nassau County?
Call NowCoverage Across Every Corner of Nassau
Nassau County packs an enormous range of housing into a relatively small area, and each part of it brings its own restoration profile. The inner-ring communities along the Queens border — Valley Stream, Elmont, Floral Park — are dense and older, with the aging plumbing and tight lot lines that complicate water and fire work. The central spine of Hempstead, Hicksville, Mineola, and Levittown is classic post-war Long Island: Levittown alone is the original mass-produced American suburb, and much of that 1950s housing stock is still in service, oil heat and all. The North Shore Gold Coast — Great Neck, Manhasset, Roslyn — adds older, larger estate homes where water intrusion hides inside complex roof and wall assemblies.
Then there's the South Shore. Long Beach, Island Park, Freeport, and Oceanside sit on or near the water, with canal-front homes and barrier-island exposure that means coastal flooding, storm surge, and tidal backup are recurring threats — and where the line between covered "sudden and accidental" water damage and excluded flood damage becomes critical to the insurance claim. Across all of it, Madison Ave Construction handles both the emergency and the rebuild as one licensed general contractor, documented for a single claim, with crews dispatched 24/7 from our Deer Park base just over the Suffolk line.
In an active emergency, call first — (844) 760-9303 — before cleaning up. Especially with soot and flood water, early documentation protects both your property and your claim.

Frequently Asked Questions — Nassau County
Do you serve all of Nassau County?
Yes — from the inner-ring suburbs along the Queens border like Valley Stream and Elmont, through the central spine of Hempstead, Hicksville, and Levittown, up to the North Shore Gold Coast around Great Neck and Manhasset, and down to the South Shore barrier-island communities like Long Beach. We dispatch 24/7 from our Deer Park base in neighboring Suffolk County.
How fast can you reach Nassau County from Deer Park?
Our Deer Park headquarters sits right at the Nassau-Suffolk line, so much of eastern and central Nassau is within our 60-minute emergency response target. For a water or fire emergency, that fast arrival directly limits how far the damage spreads before mitigation begins.
Do you handle flooding in South Shore Nassau communities?
Yes. Nassau's South Shore — Long Beach, Island Park, Freeport, Oceanside, and the surrounding canal and barrier-island areas — faces coastal flooding, storm surge, and tidal backup. We provide emergency water extraction, structural drying, mold prevention, and full reconstruction, and we document the cause of loss carefully to support the insurance claim, since flood versus sudden-and-accidental water is a critical coverage distinction in these areas.
